Tall Arrays

Arrays with more rows than fit in memory

Tall arrays provide a way to work with data backed by a datastore that can
have millions or billions of rows. You can create tall numeric arrays, cell
arrays, categoricals, strings, datetimes, durations, or calendar durations,
and you can use any of these tall types as variables in a tall table or tall
timetable. Many operations and functions work the same way with tall arrays
as they do with in-memory MATLAB® arrays, but most results are evaluated only when you request
them explicitly using gather. MATLAB automatically optimizes the queued calculations by minimizing
the number of passes through the data. For more information, see Tall Arrays .
